Hi everyone!
I am new here and I also just started to solve mathematical proofs and some of this proofs really confuse me. My teacher gave me some proofs to do voluntarily and i solved the first few but they were easier than this one:
The original text is in german but i try to translate it as best as possible
Proof that this Statement is correct:
For the sharp angles a and b is: sin (a + b) < sin a + sin b.
Note: 0<cos a< 1
I really dont know where to start and i really would appreciate any help!
